Prevent fuel backflow and keep your engine primed with the Secraft Check Valve V2. Designed for RC gas and glow aircraft, this one-way valve improves fuel system reliability and consistency.

The Secraft Check Valve V2 is a high-quality one-way fuel valve designed to improve reliability in RC airplane fuel systems. It allows fuel to flow in one direction only, helping prevent backflow, air entry, and loss of fuel prime.

This is a critical upgrade for pilots running gas or glow engines where consistent fuel delivery and easy starting are important.

What Does a Check Valve Do?

A check valve allows fuel to move forward through the system while preventing it from flowing backward. This helps maintain fuel in the line and reduces the chances of air entering the system.
